Both Drilling Rigs are accompanied with an extensive on site back up maintenance capacity (welders, spare parts, etc.) and self-contained camping facilities.

Over the past decade Frank Walsh Drilling has carried out the majority of the R.C Drilling and water supply programs at the Prominent Hill Mine Site in Northern South Australia. R.C holes have been up to 600m deep through typically South Australian very deep sedimentary cover followed by extremely
hard and abrasive hard rock basement. The water drilling program has consisted of large diameter holes up to 550 m deep.
